Prepare the apple filling by dicing tart apples and combining them in a medium saucepan with brown sugar, cinnamon, vanilla extract, butter, and caramel sauce. Cook for about 10 minutes until tender.

While the apple filling cools, make the cream cheese topping by beating softened cream cheese, powdered sugar, and vanilla extract until smooth.

Heat oil in a large skillet until shimmering. Fry each tortilla for 15 seconds on each side until golden, then fold them in half and coat with cinnamon sugar.

Assemble tacos by spooning warm apple filling into each taco shell, then top with cream cheese topping and a sprinkle of cinnamon.
